Power connector

The present invention provides a power connector, in particular, a male connector body is provided with a fixed terminal for plugging and positioning with a female connector, and is bridged and integrated by a bridge between the two fixed terminals, thereby assembling And the structure is more simple and stable, and when the male connector is inserted and removed into the female connector, the effect of effectively increasing the strength of the member, the deformation is not easy, and the damage is not easy.

According to the current type of electrical connectors frequently used in electronic devices, the universal serial bus (USB) specification of electrical connectors is the most widely used, and varies with the specifications of the universal serial bus, such as USB2.0, USB3. .0, Micro Universal Serial Bus (Micro USB), Mini Universal Serial Bus (Mini USB) or Universal Serial Bus Type-C, etc., can be used in a variety of applications, including the universal serial bus type -C specification terminal group includes upper and lower relative upper row of terminals and plural lower row of terminals, and metal separators are arranged between plural upper row terminals and plural lower row ends, in order to connect terminal groups and metals The electrical connector of the type-C specification of the general-purpose serial busbar of the baffle forming must be subjected to a plurality of processing operations, respectively, after the externally-disposed terminal blocks and the plurality of lower-end ends are externally formed with the insulating rubber seat, and the metal separator is sandwiched in the plural The upper terminal and the lower terminal of the insulating rubber seat are plastic injection processed before they can be molded into a female connector. However, in today's male connector, it is often only used for many applications. The female connector Power supply or charging is used on the device side (such as mobile phone, tablet computer, etc.), so the number of terminals used by the male connector can omit the signal terminal and only need to retain the power supply and ground terminal, but in order to be in the front type or The reverse type plug-in female connector, the plurality of power supply and the grounding terminal of the male connector are also in the upper two rows of the symmetrical position, but the position of the terminal for omitting the complex signal is a clear state, and the overall structure is complicated and the design is not easy. Generally, the male connector of the cable is in two ways, one is to directly solder the male connector to the plurality of conductors of the wire, and the other is to use the plurality of conductors of the male connector and the wire. At the same time, it is soldered to a circuit board, and after the above two methods are completed, it is required to be formed with an insulating material outside the insulator of the male connector near the soldering portion and the conductor of the wire, which is a complete wire end male connector. When the male connector used for such power supply or charging is plugged and unplugged into the female connector, the following problems may occur, and when the fixed end between the two is stressed, the structure thereof Qualitative insufficient, which in turn leads to deformation and damage to the member, and also the short life of the product is less than the drawing force intensity fall off easily deleted.

Therefore, how to solve the above-mentioned lack of inconvenience and inconvenience is the direction that the relevant industry is eager to study and improve.

Therefore, in view of the above-mentioned shortcomings, the creators have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, the new patents of such power connectors have been designed.

The main purpose of the present invention is that the body is a hollow body, and a plug-in space for inserting the female connector in the front and the back is provided in front of the body, and the two side walls of the plug space are provided. The fixed terminal for plugging and positioning with the female connector is connected to the fixed terminal by a bridge portion, and the strength of the fixed terminal structure is further improved, so When the head connector is inserted and removed into the female connector, the purpose of effectively increasing the strength of the component and not easily deforming and being easily damaged can be achieved.

The secondary purpose of the present invention is that the fixed terminal is connected by a bridge portion, and the fixed terminal can be assembled to the body once in place, thereby saving the fixing of the fixed side wall and the two side wall surfaces of the plug space. The terminals are respectively arranged in the process and time of the side wall surfaces of the plug space, thereby achieving the purpose of reducing the assembly cost.
